| Abstract | This study reviewed the placement of mass concrete under water using a tremie. Areas investigated included (a) Mixture design of tremie concrete including the use of pozzolanic replacement of portions of the cement; (b) Flow patterns and flow related characteristics of tremie-placed concrete; (c) Heat development and associated cracking problems for tremie concrete; (d) Prediction of temperatures in massive tremie concrete placements; and (e) Quality of tremie-placed concrete. Additionally, the tremie placement of a massive cofferdam seal for a pier of a major bridge and the tremie placement of a deep cutoff wall through an existing earthfill dam are examined. A recommended practice and a guide specification for massive tremie placements are provided. These items cover basic principles of tremie placement, concrete materials and mixture design, temperature considerations, placement equipment, preplacement planning, placement procedures, and postplacement evaluation. Item #12 (continued) This work is a result of research sponsored, in part, by NOAA, National Sea Grant College Program, Department of Commerce; under a grant to the California Sea-Grant College Program, #04-7-158-44121, and by the California State Resources Agency, Project Number R/E-14. |
